Is Blended Learning Effective?

Blended learning sounds like a nice idea--mixing a traditional classroom environment with online components--but is it actually effective? It seems almost intuitively obvious that it is. And with the explosion of blended course delivery in recent years, despite the dearth of research, clearly education institutions take that point for granted.
But researchers at the University of Missouri didn't want to take it for granted when it came to deciding on a delivery model for her own class. So Shawna Strickland, director of the Respiratory Therapy Program at the University of Missouri School of Health Professions, along with student Jason Domachowski, launched a study into the effectiveness of blended learning versus a traditional classroom, dubbed "The Effectiveness of Blended Learning Environments for the Delivery of Respiratory Care Education."
"I couldn't find any research on the subject of blended learning when I was trying to decide for my own class whether blended learning was effective," Strickland said through the University of Missouri News Bureau. "In theory, it sounds great, but there was really no hard evidence that it works. In addition, it is important to ask the question: 'do the students even like it?'"
The study compared two classes taught by the same teacher using two different delivery models: one purely traditional (i.e. face to face), the other blended.
The result, according to the study, was a wash. Academically, there was no statistical difference in achievement between the two classes. And there were no major differences in satisfaction levels based on subjective student comments.
According to an abstract of the report, "None of the variables showed a statistically significant difference (p=0.05). Further testing revealed an expected positive relationship between pre-existing GPA and the final examination grade as well as the final examination grade and the course grade (p=0.05). No other positive relationships were noted in course outcomes, student satisfaction or subjective comments."
